The gold and silver tailings were generated from conventional mining operations between 1992 and 1999. The original mining operation's recoveries were poor (< 30%) and considerable amounts of ore were placed in the dam. The dam has an estimated 5,137 million metric tonnes of ore, grading g/t gold and g/t silver.
